摘要

求出了γ维空间中理想玻色气体的态密度,采用Thomas-Fermi近似,导出了γ维广义幂律势阱中粒子数密度的空间分布.在此基础上,求出了原子激射器的空间有效增益范围(即γ维势阱中玻色-爱因斯坦凝聚的空间有效范围),并对其产生影响的相关因素进行了讨论.

关键词:

The density of states for an ideal Bose gas in a γ-dimensional potential is obtained. Morever, the spatial distribution of particle numerical density is derived in the Thomas-Fermi semiclassical approximation. On this basis, the valid gain range of space for atom laser (that is the valid trapped range of ideal Bose gas in γ-dimensional potential) is given, and the influence of some important factors is also discussed.
